Very convenient, even if people think you are stupid when you listen in a strange box you use like a camera.

1 mm for the diameter of you hole is really to big. I am not a big fan of formula (you can easaly find 10 different formula with different results, see here*). But clearly, 1 mm for a 28 mm focal will oblige you to very short exposures. You should try with a 0.2 or 0.3 mm hole.

ISO 200 can be OK. I use FP4+ and devellop at ISO 50. But 200 is still manageable.

Like bvy, I recommand the Populist, very fun and very good to start with.

These are the photos

The photos are all fuzzy.I guess my hand moved the camera.I did stick it to solid things, but I do not think it made the trick work.The hole it is not really round maybe.Or it's the focal length? I should redo the hole?maybe smaller?Can you guys give me an advice?
The camera is ok, I've done it so I could use it for years, I hope )

I do not have the impression you moved. It seems to me that more link to size of the hole of its shape. Aloso it is a 135 film. This is clear with pinhole very rapidly when you enlarge such format you got blur photo.

But this is pinhole and hand made pinhole, so, do not expect to have sharp pictures.

An example of what I do with matcbox pinhole, your photo are very sharp compare to this one

I love your photos.They look great.Romary maybe you are right about the size and shape of the pinhole.That is why I will try today to change it, make it better.I found an old watch , it has small pieces put small holes too.Maybe I have a chance of getting that perfect pinhole.
And Romary, can you post some more pictures done with your pinhole camera?I would really enjoy them.
